Abstract: A foam filled panel with decorative thread stitching is provided. In addition, the stitching can be sealed to prevent leakage of foam when it is injected between a substrate and a skin layer to provide a foam filled panel. The decorative thread stitching can be sewn into the skin layer of the foam filled panel before the panel is assembled and filled with injectable foam. In addition, the skin can be made via slush molding, which allows various features and details to be molded into the skin. In some instances, the stitching can be sealed by adhesively attaching an impermeable membrane along a length of the stitching, thereby covering all the openings. In other instances, the stitching is sealed by using an expandable thread. Also disclosed is a process for manufacturing a foam filled panel with decorative thread stitching.

Abstract: In a method of manufacturing an electroforming mold, a first photoresist layer is formed on an upper surface of a bottom conductive film of a substrate, and the first photoresist layer is divided into a first soluble portion and a first insoluble portion. A conductive material is thermally deposited on an upper surface of the first photoresist layer within a predetermined temperature range, to thereby form an intermediate conductive film. An intermediate conductive film is patterned. A second photoresist layer is formed on an exposed upper surface of the first photoresist layer after the intermediate conductive film is removed, and on an upper surface of the intermediate conductive film remaining after patterning. The second photoresist layer is divided into a second soluble portion and a second insoluble portion. Next, the first and second photoresist layers are developed, and the first and second soluble portions are removed.
